Energy is an essential factor in development, since it stimulates, and supports economic growth, and development in Sudan. Any form of energy can be transformed into another form, but the total energy always remains the same. Sustainable energy is the provision of energy such that it meets the needs of the present without compromising the ability of future generations to meet their needs. Sustainable energy sources are most often regarded as including all renewable sources, such as biofuels, solar power, wind power, wave power, geothermal power and tidal power. It usually also includes technologies that improve energy efficiency. This book discusses new developments in this field, as well as the impact that renewable energy, and alternative energy might have in the future. This important book gathers the latest research in the study of sustainable energy and highlights such topics as: monitoring sustainable energy development; methane; energy and territory; biodiesel production; environmental policies in an electricity sector and others.
